摘要
以骨干自交系许178背景的综3染色体单片段代换系为基础材料,利用105个SSSLs群体通过在浚县、许昌的田间试验,共鉴定出47个控制玉米开花期相关性状的QTL,包括散粉期的QTL 14个,吐丝期的QTL 16个,ASI的QTL 17个,其中,1个散粉期的QTL、2个吐丝天数的QTL和4个ASI的QTL在2种环境下被重复检测到.
A set of single segment substitution lines （SSSLs） population derived from an elite inbred line Xu 178 as recipient parent and inbred line Zong 3 as donor parent, were used as marital for QTL mapping of flowering related traits in maize. The SSSLs population was evaluated at Xunxian and Xuchang locations. A total of 47 QTL for the flowering related traits were detected at the two locations, including 14 QTL for shedding period, 16 QTL for silking days, 17 QTL for ASI. Out of them, 1 QTL for shedding period, 2 QTL for silking days, 5 QTL for ASI were detected at the two locations simultaneously.
